U74HCT564 - OCTAL D-TYPE FLIP-FLOP

General Description

The U74HCT564 is octal D-type flip-flops featuring separate D-type inputs for each flip-flop and inverting 3-state outputs for bus oriented applications.

A clock (CP) and an output enable ( OE ) input are common to all flip-flops.

Key Features

  • S.
  • 3-state inverting outputs for bus oriented.

UNISONIC TECHNOLOGIES CO., LTD U74HCT564 Preliminary OCTAL D-TYPE FLIP-FLOP; POSITIVE-EDGE TRIGGER; 3-STATE; INVERTING  DESCRIPTION The U74HCT564 is octal D-type flip-flops featuring separate D-type inputs for each flip-flop and inverting 3-state outputs for bus oriented applications. A clock (CP) and an output enable ( OE ) input are common to all flip-flops. The 8 flip-flops will store the state of their individual D-inputs that meet the set-up and hold times requirements on the LOW-to-HIGH CP transition. When OE is LOW, the contents of the 8 flip-flops are available at the outputs. When OE is HIGH, the outputs go to the high impedance OFF-state. Operation of the OE input does not affect the state of the flip-flops.
